A variant of Radio Grave which took many hours to produce. I think the effort was worth it! This is a functional Multi-font and can produce a broad range of effects, especially when used at down near the original size.
1. Use the darkest tone on the outermost concentric region and get lighter as one progresses inward.
2. Let the 5x5 region surrounding the exact center of each glyph use the lightest tone, except when this would place the lightest tone into its neighboring region.
3. Glyphs with diagonals and glyphs which use a smaller than 5x5 drawing area may bend rule 2 for the sake of more consistent and/or interesting shading.
